如何使用给定列表创建分页函数

Question

我必须创建一个分页函数询问2个arguements数组和page_number

我试图解决的任何一个项目在一个列表中，我有一些问题，这里是一个代码

def paginator(array,page_number):
    if 0 < page_number < len(array):
        obj_per_page = len(array)//page_number
        objects = len(array)
        count = 0
        start = 0
        while objects > 1:
            count += 1
            objects -= len(array)//page_number
            object_available = array[start:obj_per_page]
            print(f'this is page {count} have object {object_available}')
            start = obj_per_page 
            obj_per_page += len(array)//page_number
    
    elif len(array) <= page_number:
        for i in array:
            print(f'thi is page {i} have object [{i}]')
 
    else:
        print(array)
 
 
list = [1,2,3,4,5,6]
page_number = 3
 
paginator(list,page_number)

输出

this is page 1 have object [1, 2]
this is page 2 have object [3, 4]
this is page 3 have object [5, 6]

`此代码仅在以下情况下提供预期输出：

如果len（list）可被page_number整除，如果page_number为0，或如果page_number大于并等于len（list）`

臭虫

假设len（list）是9，page_number是（2,4,5,6,7,8）之一，9%(2,4,5,6,7,8）的剩余部分是（1,1,4,3,2,1）,因此项的数目等于remaider而缺失

我想要的东西

如果len（list）是9，page_number是4，并且我想输出如下所示

this is page 1 have object [1, 2, 3]
this is page 2 have object [4, 5]
this is page 3 have object [6, 7]
this is page 4 have object [8, 9]

如果你们有其他的解决方法，请帮帮我，分享它，我试着解释我的问题，对不起，糟糕的语法

我已经更新了数组索引，在第一页添加提醒对象。

def paginator(array,page_number):
    if 0 < page_number < len(array):
        obj_per_page = len(array)//page_number
        reminder_objects = len(array) - (obj_per_page * page_number)
        total_objects = len(array)
        count = 0
        start = 0
        first_page = True
        while total_objects > 0:
            if first_page and reminder_objects > 0:
                total_objects_current_page = obj_per_page + reminder_objects
            else:
                total_objects_current_page = obj_per_page
            total_objects -= total_objects_current_page
            object_available = array[start:start+total_objects_current_page]                
            count += 1
            print(f'this is page {count} have object {object_available}')
            start += total_objects_current_page 
            first_page = False
    
    elif len(array) <= page_number:
        for i in array:
            print(f'thi is page {i} have object [{i}]')
 
    else:
        print(array)
 
 
ar = [1,2,3,4,5,6,7,8,9]
page_number = 4

输出：

this is page 1 have object [1, 2, 3]
this is page 2 have object [4, 5]
this is page 3 have object [6, 7]
this is page 4 have object [8, 9]
